Beryllium Tellurite

Beryllium Tellurite Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Berylliumtellurite has themolecular formula of BeTeO3 and the molecular weight of 184.61 grams per mole. It can be prepared by means of the solid-state reaction:
  BeO+ TeO2+ heat ? BeTeO3
  An inert atmosphere is required. This salt is a metatellurite but its formation and physical properties have not been reported in the literature. If a solution method is used, the result is likely to be quite different in that a hydroxy-tellurite is formed:
  BeCl2+ Na2TeO3 ? [Be(OH)]2TeO3
  Additionally, this compound can be prepared by reacting tellurium dichloride in a solution of beryllium chloride:
  BeCl2 + 2TeCl2 + 4H2O ? Te+ [Be(OH)]2TeO3 + 6HCl
  Nonetheless, there is absolutely no description of these compounds in the literature and whether a hydrate appears remains unknown.
